BU5255SHFV-TR

Comparators Overview

The BU5255SHFV-TR is a single-channel CMOS analog comparator manufactured by ROHM Semiconductor. It features a wide operating supply voltage range of 1.8 V to 5.5 V for single-supply applications, enabling low-voltage operation with minimal current consumption. The device incorporates an input full-swing capability and utilizes a push-pull output configuration. Key electrical specifications include a maximum input offset voltage of 6 mV at 3 V, a typical response time of 1.6 µs, and a high voltage gain of 90 dB. It maintains a maximum input bias current of 1 pA and offers a power supply rejection ratio (PSRR) of 80 dB. The component operates within an extended temperature range from -40°C to +105°C and is housed in a compact HVSOF-5 package.

Comparators Feature Summary

• Portable consumer electronics requiring small form factors
• General-purpose signal comparison circuits in industrial equipment

Comparators Procurement Notes

Verify the specific suffix 'SHFV' against the manufacturer's official datasheet to confirm the exact pinout and thermal characteristics, as variations exist within the BU5255 series. Ensure the ordering part number matches the required tape-and-reel quantity of 3000 units. Cross-reference the RoHS compliance status and lead times directly with authorized distributors or the manufacturer's sales channels prior to finalizing procurement plans.

Comparators Selection Notes

Select this component when a single-channel comparator with push-pull outputs is required for low-voltage systems. It is suitable for designs needing wide input common-mode ranges extending to the supply rails. Consider this part over open-drain alternatives if direct logic interfacing without external pull-ups is necessary. Verify that the 1.6 µs response time meets the speed requirements of the target application circuit.
